VERTICAL ADDITION: In graphical analysis, the technique of combining two curves by adding the value of the variable on the vertical or Y axis for a given value of the variable on the horizontal or X axis. This is commonly used for deriving the demand curve for a public good from a set of individual demand curves. The demand price that each individual buyer is willing to pay is added for a given quantity to identify the total benefits obtained.

Business Cycles
To purpose of this lesson is to examine the nature and causes of macroeconomic instability, which goes by the handy title business cycles. Business cycles are the recurring expansions and contractions of economic activity that generate the problems of unemployment and inflation. This lesson explores how business cycles can be stabilized with the goal of lessening unemployment and inflation. - The notion of business cycles is introduced in the first unit of this lesson, with an eye on what they are and why they are important to study.
- The four components of a standard, simple business cycle -- expansion, peak, contraction, and trough -- are then presented and discussed in the second unit.
- The third unit is devoted to several key measures of business cycle activity, especially leading, lagging, and coincident indicators.
- A couple of the most often discussed causes of business-cycle instability -- investment and politics -- are discussed in the fourth unit.
- The fifth unit closes out this lesson with an introduction to the expansionary and contractionary economic policies used to stabilize business cycles.

SLOPE, CONSUMPTION LINE The positive slope of the consumption line is also termed the marginal propensity to consume (MPC). This slope is greater than zero but less than one, reflecting induced consumption and the Keynesian psychological law of consumer behavior that consumption increases by less than the increase in income. The slope of the consumption line provides the foundation for the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process.
